what is best approach to calculate age to allow/disallow registeration? For example if want to allow the persons above 18 years to register, how should i calculate the age? I saw some example on google where they convert days first and then make it to years, but i think it does not give the exact age? it gives only round about? Is there any good way to calculate the age ? Any example would be appreciated.
thanks

I recommend using a checkbox that has some text to the effect of "by checking this box, you indicate that you are 18 years of age or older." You can't verify the age anyway, because you can't check an id. People that are under 18 will just create new birthdates for themselves if they really want to register.

Indeed Wirehopper is once again correct. If someone wants to get in your site they will just lie about when they were born. However, (if you are in the US at least) you can ask them to check a box, and this check will count as an 'electronic signature' so even if they lie you are covered because they have in effect sworn they are of age.

Then they could refer to the link already provided in the post by wirehopper: http://www.hotscripts.com/forums/php...t-age-dob.html
